MECHANISM FOR UTILIZING THE POWER OF ENGINES OR MOTORS.

SPECIFICATXON forming part of Letters Patent No. 697,175, dated April 8,1902.

Application filed July'26. 1901. Serial No. 69,763. (No model.) l

To a/ZZ whom it may concern:

Beit known that l, HENRY lV. SCHLOMANN, a citizen of the United States,and a resident of the city, county, and State of New York, have inventedcertain new and useful Improvements in Mechanism for Utilizing the Powerof Engines or Motors, of which the following is a specification.

My invention more especially relates to en gines or motors of the classdriven by intermittent impulses acting in one direction only; and itsobject is to increase both the power and the smooth running of suchmotors; to which end my improvements consistin certain novelcombinations and organizations of instrumentalities hereinafterdescribed, and specified in the claims at the end of this speciication.

The accompanying drawings show so much of the apparatus as is necessaryto illustrate my invention embodied in a single-acting gasengine.

Figure l is a side elevation; Fig. 2, a plan view, and Fig. 3 amodification.

The drawings show the prime motor 1, adapted for actuating an ordinarydynamo 2, connected by suitable conductors 3 3 with a series ofincandescent lights 4.

Fig. 2 shows ordinary fly-wheels 9 9, mounted on a driving-shaft 8,actuated from the prime motor in the usual way. An independent orintermediate auxiliary balance-wheel 5, mounted on a suitable shaftbetween the driving-shaft and dynamo, is provided with a pulley 7,driven from the large pulley 6 on the driving-shaft. The usualpreferred speed for this auxiliary balance-wheel is double that of theshaft S; but it can be run with good results at as high a speed as fourtimes that of said shaft, or even faster, if desired. Fig. 3 shows thisauxiliary balance-wheel as mounted directly on the shaft of the dynamo2.

No matter how large or heavy the ily-wheels of ordinary engines may bemade they cannot store power so that it can react and be given back tothe engine to be transmitted to the load with the same efficiency as canbe attained by a balance-wheel running at a higher speed located betweenthe motor and its load or on the shaft carrying the load if such shaftis carried at a higher speed than the crank or driving shaft.

The auxiliary balance-wheel 5 is not necessarily of large diameter, butmust be of great weight. The largest possible proportion of such weightis preferably put in its periphery, and its momentum being proportionalto its velocity is much greater than that of the ordinary fly-wheelrunning at the speed of the crank-shaft. This organization reinforcesand renders more uniform the motion of the large balance wheel orwheels. The ordinary fly-wheels have neither the impetus, centrifugalforce, nor momentum requisite for such work. My im prove ments areadaptable to thermodynamic engines and motors, and especially adaptableto single-acting engines employed for electric lighting, for whichpurpose smooth uniform running is required.

The tendency of my improved organization is to maintain the full speedof the engine at the moment of the greatest pressure given by theimpulse on the piston during its outstroke throughout the succeedinginstroke or immediately-following revolutions or until the piston hasreceived another impulse. The greater the number of revolutions theengine or motor makes to an impulse on the piston the greater will beits efficiency.

In the construction of my improved auxiliary balance-wheel the mass ofweight should be so proportioned as to give the largest possibleeficiency relatively to the character of the work to be done and therelative diameter of all pulleys should be such as to give the requiredspeed for attaining the best efficiency. These details involve only thewellknown skill of the constructor.

The movement of the ordinary single-acting engines or motors as nowbuilt is apt to be uneven or irregular, owing to the character of theimpulses, and double-acting engines are liable to the same defect in alesser degrec. Such engines are therefore not well adapted to electriclighting, owing to the flicker or pulsation of the lights caused by thisuneven movement. My improvements render the speed uniform and maintain abrilliancy and intensity of such lights with very slight if any changeregardless of any class IDO or character of the prime motor employed.The power of the impulses received on the piston is distributedthroughout the revolution of the crank and immediately succeeding suchimpulse and its succeeding revolutions or between the impulse received,thus maintaining a uniform speed, and as all the pressure on the pistonsis thus utilized without increased consumption of fuel or gas theefficiency of the motor is largely increased.

Figs. l and 2 show the intermediate or independent auxiliarybalance-wheel on an independent or separat-e shaft located between theordinary balance-wheel shaft and its load and so driven from thedriving-shaft as to run at a much higher speed than the engine or motor.

Fig. 3 shows the auxiliary balance-wheel mounted directly .on the shaftcarrying the dynamo or load, which construction can only be used whensaid shaft runs at a considerably higher speed than the engine, whichfeature of increasedspeed is an essential feature of my invention, forin this manner the impulse or impact given to the piston by the initialand sudden -pressu-re thereon of the steam, compressed air, oil, or gasexploded in the cylinder is transmitted to the high-speed balance-wheel,yby reason of the centrifugal force and momentum of which it reacts onthe motor and renders its motion uniform.

What I claim herein as own invention isl. vThe combination of a mainfly-wheel, its shaft and an auxiliary balance-Wheel mountnew and as ofmy ed on a shaft separate from the main fly-Wheel shaft, but drivendirectly from it vat a higher speed, substantially as and for thepurpose set forth.

2. The combination of a main fly-wheel, its shaft and an auxiliarybalance-Wheel mounted on a shaft separate from the main Iiy-Wheel shaft,between said fly-wheel shaft and its load, and driven directly from thedrivingshaft but at a higher rate of speed, substantially as and for thepurpose set forth.

3. The combination substantially as hereinbefore set forth of a primemotor, its driving-shaft, a fly-Wheel thereon, an auxiliary balancewheel having a preponderance of weight in its periphery and mounted onan independent or separate shaft and means for driving said auxiliarybalance-wheel at a rate of speed higher than that of the ily-wheel.

4. The combination substantially as hereinbefore set forth of a primemotor, its driving-shaft, a fly-Wheel thereon, an independent orseparate shaft, a motor or generator driven therefrom, an auxiliarybalance-wheel mounted thereon, and means for driving the auxiliarybalance-wheel at a rate of speed higher than that of the fly-Wheel.

lSigned at New York, in the county of New York and State of New York,this 24th day of July, A. D. 1901.
